Filed: 1989-09-20
Abstract: PURPOSE:To obtain the twice large light quantity by moving both of 1st linearly polarized light and 2nd linearly polarized light orthogonal therewith by as much as half the picture element on a photoelectric conversion means. CONSTITUTION:The incident light past an image pickup lens 1 is photoelectrically converted 4 through 1st and 2nd photoelectric elements 2, 3 and is outputted to an output terminal 8. The 1st element 1 is installed with inclination by an angle a with the plane perpendicular to the optical axis and the 2nd element 3 with inclination by an angle (b). A synchronizing signal generator 5 generates pulse at, for example, every field and supplies field pulses by 1st, 2nd driving means 6, 7. The 1st means 6 applies the impressed voltage varying by each field to the 2nd element 2 and the 2nd means 7 applies the impressed voltage varying by each field to the 2nd element 3. As a result, the refractive index n1 with the linearly polarized wave of the 1st element changes by each field and the refractive index n2 to the 2nd linearly polarized wave orthogonal with the 1st linearly polarized wave of the 2nd element 3 changes by each field. Both the 1st and 2nd linearly polarized light rays are subjected to the shift by as much as the half picture element, by which the apparent resolution is doubled.

Filed: 1990-09-17
Abstract: PURPOSE:To enable reliability to be improved and cost to be reduced with a simple circuit configuration by dividing a phase difference signal which is in proportion to a multi-phase AC voltage by the amplitude and reducing influ ence of temperature drift. CONSTITUTION:After a three-phase AC voltage is rectified by an all-wave rectification circuit 12, it is converted into digital data by an AD converter 13 and a CPU 14 which controls an entire device reads a voltage amplitude V. Then, an inverse number of the voltage amplitude V is calculated by software utilizing spare time of the CPU 14 and is output to a multiplication-type DA converter 4E, where VsinDELTAtheta which is obtained from a three-phase AC voltage through a three-phase and 2-phase conversion circuit 1 is multiplied by the inverse number of its amplitude V, thus enabling sinDELTAtheta to be output. The detection phase theta' is obtained through a low-pass filter 8 and then a counter 11, thus enabling influence of change in voltage amplitude to be eliminated with a simpler circuit.

Title: Reference voltage generating circuit
Inventor: WARITA HIROHISA
IPC: G05F3/02
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To realize a reference voltage generating circuit which can generate a reference voltage with high precision over a wide temperature range although the circuit configuration is simple. SOLUTION: At a reference voltage generation part 2, the emitter currents I1 and I2 of both transistor(TR) Qn1 and Qn2 are prescribed by the band gap between the both and flow to resistances R2 to R4. Consequently, the base voltages of the TRs Qn1 and Qn2 are held at a constant reference voltage VREF as long as the temperature does not vary. A temperature correction part 3, on the other hand, divides the reference voltage VREF by resistances R31 and R32 and is applied to the base of a TR Qp31. As the temperature rises, the base-emitter voltage of the TR Qp31 drops. Consequently, the TR Qp31 turns on and a current Iadj corresponding to the temperature begins to flow to the resistance R4. Consequently, the drop of the reference voltage VREF caused by the temperature rising is canceled.

Inventor: HAMAI TSUNEO
IPC: G06F7/544
Filed: 1984-11-19
Abstract: PURPOSE:To simplify the addition/subtraction of constants at a high speed by supplying the output of an accumulator register as an input of a pre-load control circuit and also supplying the input given from an external terminal as the other input of said pre-load control circuit. CONSTITUTION:A tristate buffer 7 is set in a high impedance state in case the selection of fields is carried out by a field selection signal FC. Thus an accumulator register 6 is separated electrically from an external terminal 8 to eliminate the mutual effects between the register 6 and the terminal 8. When no selection of fields is not carried out, the register 6 is connected to the terminal 8. Then the storage value of the register 6 is delivered through the terminal 8. Furthermore an accumulation control circuit 10 controls the data delivered from the register 6 based on the accumulation signal ACC, addition/subtraction signal ADD/SUB, pre-load control signal PC and field selection signal FS respectively and then sends the data to a totalization circuit 4. Thus the addition/ subtraction is possible between the data of the register 6 and the data supplied through the terminal 8.

IPC: H05B6/12
Filed: 1989-09-20
Abstract: PURPOSE:To continue induction heating stably even if an object to be heated is small or the object to be heated is moved on a heating plate and to extend the cooking capability of an induction heating apparatus by making load discrimination level variable in a load discrimination circuit by a switch. CONSTITUTION:A load discrimination circuit 18 determines whether there is an object, that is, load, to be heated by induction heating based on the load discrimination level. The presence of load is surely determined even if the load is small or moves by making the load discrimination level variable by a varying means 2. When load is taken out and no load is discriminated, a timer delay circuit 19 starts and an inverter circuit 6 is controlled to stop only in the case that no load condition continues for a specific period, and therefore, induction heating of an object to be heated can be re-started within the specific period and continuous operation can be done without re-starting operation. In this way, stable induction heating is carried out even if an object to be heated is small or moves and continuous heating is able to be carried out if it is within a short period after the object to be heated is taken out.
